Abstract
Abstract Conventional dental floss is provided with loops at convenient intervals along its length. The person using the dental floss can insert a finger from each hand into two adjacent loops to obtain a firm grip on the dental floss while it is being used to remove particles from between the teeth. The dental floss with the loops on it is rolled into a coil in the usual manner and placed in a container from which it can be drawn for use.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
212 words
In a device for cleaning the teeth of a human being; a continuous length of thread adapted to be inserted between the teeth and drawn longitudinally for removing particles of food and the like from between the teeth; a plurality of finger loops disposed at intervals along said length of thread to define useable lengths of thread for cleaning teeth between them, such loops being formed by looping the dental thread itself so that the user may insert a finger of each hand into the two loops for gripping the thread while drawing it back and forth between the teeth in a cleaning operation; a knot in the thread at each of said finger loops to secure the loop; a cutoff length of dental thread between each of said useable lengths to provide a length of thread that may be severed for separating the useable lengths of thread from the continuous length of thread without interrupting the useable lengths of thread; and the continuous length of thread with said finger loops attached is wound into a coil from which it may be withdrawn and the useable lengths of thread each with two finger loops attached may be individually separated from the continuous thread by severing the continuous thread at said cutoff lengths.

Dependent Claim

Claim 3
Dependent Claim
103 words
A teeth cleaning device according to claim 1 including; a container for containing said continuous length of thread in a sanitary condition; a reel rotatably supported in said container so that said continuous length of thread can be wound on said reel to form said coil and may be unwound from said reel to withdraw the dental thread from said container; and a knife on said container in position to engage said dental thread at a cutoff length to sever it and thereby separate a useable length of dental thread with its two cooperating finger loops from the continuous thread on said reel.
